PATENT @rrrcn OF NEW YORK, N. Y.

APPARATUS FOR AUTOMATICALLY LUBRICATlNG STEAM-CHESTS.

SPE CIPICATION forming part of Letters Application filed July 12, 1886.

To all whom it may concern.-

Be it known that I, THOMAS FITZPATRIOK, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented a new and useful improvement in Apparatus for Automatically Lubricating Steam-Chests, of which the fol- My invention relates to apparatus for automatically supplying lubricating-oil to the steam-chests of steam-pumps or steam-en gines, and has for its object to permit of supplying oil' to the steam-chests of one or more pumps or engines simultaneously and without the employment of the usual oil-cups or lubri cators.

The essential features of my invention are illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of the complete apparatus. Fig. 2 represents a ver tical section of the oil-reservoir. Fig. 3 represents a similar section of a visible feed arranged in one of the oil-tubes.

Similar letters indicate similar parts.

The letter A designates a portion of a steam boiler, to which is connected by means of pipes B B the steam-chest O of a steam-pump.

D indicates an oil-reservoir, the upper end or part of which is connected by means of tubes F F T3 with the steam-pipe B, and the lower part of which is connected by means of an auxiliary pipe, B with the steam-pipe B, so that if said reservoir is supplied with oil and steam is admitted to its said lower part the oil has a tendency to flow from the reservoir through the tubes F F 15 to the steampipe B, where it commingles with the steam, so as to enter the steam-chest together therewith, a uniform pressure of steam being main tained above and below the oil from the pipes B B respectively, and its discharge thus being due solely to the relative specific gravity of oil and water.

In the steam-pipes are arranged valves t i, for regulating the supply of steam to the steam-chest O and oil-reservoir D, respectively, and in the oil-tubes are arranged cocks G o 0, for regulating the flow of oil to the proper steam-pipe, the cocks o 0 being at Patent No. 884,354, dated June 12, 1888.

Serial No. .207, 774. (No model.)

opposite points in relation to a glass tube, H, which is arranged in the oil-tube F for the purpose of rendering visible the feed of the oil.

To the top of the oil-reservoir is connected at filling-cock, Z, through which the oil is to be supplied thereto, and an air-cock, s, which is to be opened during the filling operation, while to the bottom of the reservoir is connected a drain-cock, a, for emptying it of the water of condensation. In filling the reservoir the steanrvalve z" and oil-cock G are to be closed, in order to disconnect the reservoir from the steam-supply source. A gage, 1), connected to the side of the reservoir, serves to indicate the quantity of oil therein.

The visible-feed tube H is held between two end heads, H H, (see Fig. 3,) which are connected together by means of an arm, H and within said tube is arranged a nozzle, K, forming a contracted opening for the escape of the oil to the steau1-pipe. On the lower end of the nozzle K is formed a flange, and into the head H is fitted an annular nut, P, which bears against said flange of the noz- Zle, as shown, for holding the latter in position.

In carrying out my invention, the reservoir D may be placed in, for example, the boilerroom, convenient of access to the engineer, and separated from the apartment where the pump or pumps are located, as indicated in the drawings, the valve G, in that event, serving to control the escape of oil directly from the reservoir.

My invention is of especial advantage for lubricating the steam-chest'of a series of pumps used for ice-machines or other purposes in breweries; but it is evident that it may also be used in connection with steamengines generally.

In Fig. 1 I have indicated a supplemental oil-tube, F having a suitable cock, i for effecting the desired connections with additional pumps.

What I claim as new, and desire to obtain Letters Patent for, is-

In an apparatus for lubricating steam-chests, the combination of the pipe B B, connecting the boiler with the steam-chest, the oil-reservoir D, the pipe 13 connecting the pipe B In testimonythatlclaim theforegoing as my with the lower part of the oi1-reservoir, the invention I have signed my name, in presence pipe F F F connecting the upper part of of two witnesses, this 8th day of July, 1886.
